@swordzanderson5352 Grids only SEEM inefficient for transportation, because poor hierarchical organization is usually being applied. NYC is not sustainably denser and easier to traverse than DC merely because of DC's height limit... Also the advantages of hexagons emerge only when they are all the same size (which is not true of rectangular grids). If the base unit were small enough to be easily conformable to natural terrain, the percentage of space with limited usefulness goes way up. Green space is essential, but it is better in larger chunks...

@swordzanderson5352 The 90-degree turn is only congested if multiple vehicles want to make the turn at about the same time. It's not a condition that is all that easily achieved... thus for traffic the grid works most of the time and the problem-solving focus is on the 10% or 20% of intersections on a larger road. There are more problems where the road network is like a tree than where it is like a grid. Regardless of the availability of buses and trains, they aren't a complete replacement for the roads themselves. There are deliveries and other trips that don't fit the bus or train pattern. In any case, the evolution of any railroad or road is that it is a path along or through someone's property. Without the division of property being hexagonal (which would require a whole lot more cooperation than normally exists!) roads weren't going to be that way.

@alanlight7740 Setbacks are one of the prime motivators for making a lot rectangular, because the area out of bounds per a setback is minimized when the angles are at 90 degrees. Of course, the rules don't have to be set up to make an angle punitive... but they almost all are.
